simple in design and may be easily cleaned, adjusted and
repaired. If the installation is accessible, servicing may be
completed without disconnecting the valve.

maintained to provide best performance. Frequency of
cleaning depends on quality of local water conditions and
usage. (See Maintenance Guide and Record MGR-1000).
